Answer:
It will take 950 million years for this amount of urea to be hydrolyzed under the same conditions in the absence of urease.
Explanation:
Given that:
- In the presence of urease:
Urease enhances the rate of hydrolysis by = 10^14
Time taken in hydrolysis is 5 min
- In the absence of urease:
Time taken in hydrolysis will be = 5 min x 10^14
Now, converting minutes into years
Time = (5 min x 10^14) / (60 min/hr x 24 hr/day x 365 days/year)
Time = 9.50 x 10^8 years
Time = 950 X 10^6 years
Time = 950 million years
I believe its Sodium Chloride.

The Answer is : 1830 mmHg considering sig figs
Answer:
0.348 moles Ar
Explanation:
You can determine the moles of argon (Ar) by multiplying the given mass by the atomic mass of argon. This number gives the mass in grams per 1 mole. It is important to arrange the conversion in a way that allows for the cancellation of units. The final answer should have 3 significant figures to match the sig figs of the given value (13.9 = 3 sig figs).
Atomic Mass (Ar): 39.948 g/mol
13.9 g Ar 1 mole
----------------- x ------------------ = 0.348 moles Ar
39.948 g
